The seal of the province shows two mythical lions, called singh, facing the chedi Pra A-non, in the temple Wat Maha That in the city of Yasothon. In the legendary account of the founding of the city, a lion came out of the forest when the site was chosen; hence the city was called Ban Singh Tha (Thai: บ้านสิงห์ท่า), Home (of) Imposing Lion. (For facts behind the legend, and of two men called Singh, see the city's history).

Rocket Festival (Thai: งานประเพณีบุญบั้งไฟ) - Yasothon is famous for its Rocket Festival, held every year in May. Originally a fertility rite, it has become the major festival of the year in the region.

The festival is held on every second weekend of May at Phaya Taen Park. Yasothon locals believe that the festival pleases the gods and spirits which ensure adequate rain and food.

Each rocket is decorated with Thai traditional patterns in gold. It is said that rocket makers spend months in cutting the pattern before gluing it to the rocket. The rocket head will be decorated differently, but the most popular figure is a Naga spraying water. Rocket heads may be found decorated with other figures. All are related to rain-beseeching legends.

There are various types of rockets, namely Bang Fai Kilo, Bang Fai Muen, and Bang Fai Saen. Bang Fai Kilo means the rocket contains a kilogram of gunpowder. Bang Fai Muen contains 12 kilograms of gunpowder and Bang Fai Saen contains 120 kilograms of gunpowder. After making decision what type of rocket to make, the villager will make it themselves or assign a specialist. Making a rocket requires a specialist who can calculate proper proportions of gunpowder and charcoal, otherwise, the rocket will explode at launch.

The celebration lasts for several days and peaks on the final day with serial firing of the makeshift bamboo-rockets, some up to 10 meters in length that ascend to 10,000 meters. The festival grounds and firing takes place in a municipal park. The festival and parade takes place on Yasothon's main street.

Rockets are individually judged by a committee and the respective winners take home attractive prizes. Misfiring rockets and poor performers are punished immediately by tossing of the entire rocket crew in mud holes by their competitors.

Garland Festival (Thai: งานประเพณีแห่มาลัย) - The ancient festival of Ban Yardfah, Amphoe Maha Chana Chai, is held annually on Makha Bucha Day. Buddhists believe that on that day, the Buddha comes back from the heaven after preaching to his mother. Angels welcome him back with flowers and rice. Such belief is turned into tradition when villagers make beautiful garlands from rice (the rice will be baked until it pops like popcorn). Today the rice garland, 4-6 metres long, is decorated with flowers and beads. The garland will be displayed in a beautiful parade, and used for decorating temple pavilion a day before Makha Pucha.
